    The study defines acetabular angles as anatomical anteversion (AA) and anatomical inclination (AI), measurable only in 2D planes.

  • 2

    3D CT scans provide more accurate acetabular anteversion measurements than 2D scans, but accuracy depends on pelvic positioning.

  • 3

    Retroversion of the acetabulum can lead to instability, mechanical impingement, cartilage lesions, and early osteoarthritis.

  • 4

    The study aimed to measure the true anteversion angle (AV angle) in a healthy population using 3D reconstructions.

  • 5

    258 hemipelvises were analyzed using 3D models to calculate the true AV angle, improving the understanding of acetabular orientation.
